Rockland Hosts OMG Ocean Microstructure Glider Workshop in Halifax

It has always been ingrained in Rocklands identity to actively collaborate and empower scientists to achieve their goals. In line with this mission the Rockland Scientific team based at COVE (Centre for Ocean Ventures and Entrepreneurship), in Halifax, Nova Scotia, had the opportunity to organize an Ocean Microstructure Glider (OMG) workshop for a group of Dalhousie University physical oceanographers and glider technicians.


The workshop took place at COVE, in early September 2023, where the Dalhousie team gained knowledge of ocean turbulence theory, while also exploring the functions and capabilities of the OMG – which includes the Rockland MicroRider-1000 Turbulence Module for gliders. The workshop featured a hands-on training session aboard a Connors diving vessel departing from COVE. Collaborating with the Dalhousie Glider group (CEOTR), an OMG was deployed in the Bedford Basin, where it performed numerous test dives. Workshop participants learned to prepare and deploy the OMG system. Furthermore, alongside the OMG, a Rockland Scientific MicroCTD was deployed in both downward and uprising configurations, aiming to compare turbulence data collected by these two distinct instruments.




The workshop concluded with instrument maintenance and technical instruction on the use of microstructure probes, as well as the processing of turbulence data obtained from gliders. The workshop provided valuable learning opportunities for both the Rockland and Dalhousie teams. Rockland looks forward to ongoing collaboration with the participants of the Dalhousie OMG workshop, while they prepare for their future deployment in the Labrador Sea.


Rockland Delivers Turbulence workshop at the National Oceanography Centre (NOC) for the Marine Autonomous Robotics Systems (MARS) Group

Rockland Scientific provided an in-person, week-long Turbulence Workshop at the National Oceanography Centre Southampton (NOC Southampton) from November 28 to December 2, 2022. Although we have been providing frequent web-live training events to customers around the globe, this was the first in-person workshop since the pandemic. Participants for this workshop were from the University of Southampton, NOC Liverpool, and NOC Southampton. Members of the Marine Autonomous Robotic Systems (MARS) group work out of NOC Southampton and operate the Autosub Long Range AUV (a.k.a Boaty McBoatface), as well as NOC’s fleet of Ocean Microstructure Gliders (OMG).  

 The workshop allowed for the introduction of one of Rockland’s newest members, R&D Scientist Dr. Anneke ten Doeschate, who provided instruction on ocean turbulence theory, time series analysis, and processing of turbulence data obtained from autonomous robotic vehicles. Anneke was able to draw on her previous experience with turbulence measurements and air sea interaction research to add to many interesting discussions during the week.  

 In addition to providing educational content on ocean turbulence theory and data processing, the workshop provided technical instruction on the use of Rockland’s MicroRider instruments and microstructure probes, which are integrated on NOC’s Boaty McBoatface and Slocum Glider OMG’s. Cross-pollinating discussions from Rockland and participants occurred throughout the week and showcased how strong collaborations between research teams and industry can lead to improvements in scientific data collection techniques and technology.  Rockland enthusiastically looks forward to our continued work with all the NOC Workshop participants.  


VMP-250 Recovery

Rockland a Proud Partner of the 2021 AMAZOMIX Cruise

AMAZOMIX is a multidisciplinary oceanographic expedition exploring how the mixing of the Amazon River with the Atlantic Ocean impacts the biology, chemistry, and physics of the ocean. Indeed, the Amazon River plume carries large volumes of fresh, turbid, nutrient-rich water to a narrow coastal strip. It is a place of high phytoplankton production that has beneficial effects on the entire food chain – but also a place where turbulent processes can lead to an irreversible mixing of waters and changes to their properties along the coast. These interactions at the Amazon River outflow area affect many aspects of biodiversity, geomorphology, and physical processes.  

To help better understand turbulent mixing, the scientific crew aboard the R/V Antea is deploying a physical oceanography instrument known as the Vertical Microstructure Profiler (VMP), made by Rockland Scientific. The VMP-250 measures the turbulence generated by eddies at a millimeter scale. Turbulent mixing is the physical process that causes different layers or bodies of water to irreversibly combine. Assessing how layers in the ocean interact is key to modelling many ocean processes including nutrient transport, atmospheric carbon absorption, deep ocean circulation, heat flux, etc. Measuring the mixing intensity of these processes will provide greater understanding of biological resources and climate change. On the AMAZOMIX expedition, the VMP-250 is linking ocean physics with ocean chemistry and marine biology.  

Rockland is proud to be the only invited industry partner in this important and high-profile scientific campaign. It has always been part of the Rockland’s DNA to actively collaborate and empower scientists to achieve their goals by providing hands-on support. This will maximize the chances to collect good and valuable datasets with the Rockland Scientific instrumentation.

Swiss Limnologists Benefit from Swift Support & Loaner MicroCTD

Earlier this year, researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) were experiencing challenges with data from one of the shear channels on their MicroCTD. However, Rockland manufacturing and support teams quickly provided a loaner MicroCTD to help EPFL continue their seasonal study from their Léman exploration platform (LéXPLORE).

Rockland’s fast responsiveness and logistical capabilities provided for rapid delivery of the loaner MicroCTD. This enabled the EPFL team to conduct their periodic measurements without disruption. 

Some call it Lake Geneva (English), others call it Lac Léman (French). This beautiful lake sits on the border between Switzerland and France, and it receives a lot of scientific attention. “LéXPLORE”, which stands for “Léman exploration”, is the name for a scientific floating platform located on the lake off Lausanne. The platform is equipped with cutting-edge scientific instrumentation for simultaneous biological, chemical, and physical measurements at high resolution. 

As one can see from the pictures on the home page of the LéXPLORE platform (, Rockland Scientific equipment is an important part of the equipment pool. Here is a video of the LéXPLORE platform taken from the perspective of a MicroCTD. 

Drawing of Lake Geneva

Dr. Sebastiano Piccolroaz, an emerging scientist at EPFL, is very active in collecting microstructure data in the lakes. Dr. Piccolroaz has collected more than 900 MicroCTD profiles just in the past year. 

Sebastiano commented, “we take microstructure profiles nearly on a weekly basis (both upward and downward) as we are interested in seasonal and sub-daily turbulence and gas-flux patterns. Having the loaner instrument in such a short time was therefore a great support from Rockland as it allowed us to keep pace with our regular weekly fieldwork. On top of this, I should add that the same week we received the loaner instrument, we contributed to an important 48h monitoring campaign in Rotsee (close to Luzern), where colleagues at EAWAG are investigating horizontal flows resulting from nearshore night- time cooling with ADCP and tracer measurements. Having the loaner MicroCTD with us was definitely a big plus!”. 

Loaner MicroCTD at Rotsee

Rockland’s continuing support was further demonstrated this Spring when our Sales & Support Manager for the Europe, Middle East & Africa (EMEA) region, Romain Tricarico, had the opportunity to travel to Switzerland to work with researchers from EPFL and Swiss Federal Institute of Aquatic Science and Technology (EAWAG) on the LéXPLORE platform.

The focus of the trip was a two-day microstructure workshop organized by EPFL and EAWAG to discuss: 

  1. Best practices to operate Rockland profilers 
  2. MicroCTD-VMP data inter-comparison 
  3. Post-processing analysis 

Notably, the fun part of the workshop happened during a field testing and deployment of a whole “zoo” of Rockland equipment as shown in the picture below. 

Zoo of Rockland equipment

The VMP-500 is more than ten years old and was custom built by Rockland for Swiss researcher Prof. Alfred Wüest, whom everyone knows as Johny. Johny is the Swiss Grandmaster of limnology, having contributed numerous seminal publications on deep lake mixing and inspiring the next generation of microstructure expertsRockland looks forward to supporting this next generation!

All in all, Rockland takes pride in providing quick support to its customers and Romain’s presence at the workshop. Together with the guest web-live appearance of Dr. Rolf Lueck (Rockland co-founder and staff scientist) during the data processing session was just another testimony of Rockland’s mission to empower our customers to achieve their turbulence measurement goals and help scientists better understand climate change!

Rockland Scientific’s New Data Logger Delivers Improved Software Experience and Simplifies Connectivity with Instruments

The new Rockland Data Logger (RDL) is now equipped in the current production of Rockland instrumentation. The RDL represents an evolution in our core instrument technology with modernized components and firmware that provides users with a simplified software interface and easier connectivity & configuration.

The RDL’s capabilities far outpace those of the previous CF2-generation of data loggers by delivering enhanced data acquisition, transmission options, and on-board data analysis. 

This includes the option for new, dual-functionality of internal recording and real-time output (with properly equipped cable & winch system) on our line of Vertical Microstructure Profilers (VMP). On-board data analysis is achieved through enhanced integration with autonomous robotic vehicleswhich includes soon-to-be released In-Situ Data Processing (ISDP) that will allow for processed turbulence data to be transmitted to shore via the vehicle’s satellite telemetry system.

RDL Improvements

The RDL is designed by Rockland to meet the next generation of turbulence instrumentation. This provides us with the added benefit of improved revision generation, as well as controlling production and delivery of this core component – instead of being subjected to the current global microchip shortageThis translates to consistent delivery of Rockland instruments to our customers that are ready for deployment!

Instrument Communication: The RDL no longer requires Motocross Terminal and RSILink software (used for CF2 instruments) to communicate with a PC. Instrument configuration can now occur via the Zissou Essentials software (v1.6 and higher). Data transfer has been simplified by the fact that the RDL behaves like a USB Thumb Drive. When the USB connector is plugged into your PC, a drive will appear for two way transferring of files. 

Available Memory: RDL instruments have 64 GB of embedded memory with larger capacity options available. This is an upgrade from the CF2 standard memory which was 4 GB.  

Clock Battery: The RDL uses a CR2032 Lithium battery that is expected to last 4 years minimum compared to the CR123 battery used in CF2 instruments that must be replaced by the user at least once per year.

Built-in Backup Power Source: The RDL has a built-in super-capacitor which acts as a backup energy source to ensure that data logging can shutdown properly when power is removed. The helps prevent the loss of data in the event of power failure.

A Key to Our Mission

The RDL is a key piece of technology to ensure the success of our customers and Rockland’s mission to improving the measurement and analysis of ocean turbulence. 

Contact Rockland today to discuss how our solutions will help you reach your measurement goals. 

Additional Information about the RDL

Serial Numbering: RDL instruments have serial numbers 400 or greater. 

Data Processing: The Data Processing experience will remain the same, however the latest version of our ODAS MatLab Library or Zissou software will be required to process data files (.P) from both CF2 and RDL instruments. Please use ODAS Matlab Library v4.4.08 or Zissou Essentials v1.6 (or newer versions). 

Integrated Systems (Including MicroRiders and MicroPods): Rockland Data Loggers on integrated systems such as ocean gliders may require the platform to have specialized software designed by the platform manufacturer to control your microstructure instrument. Existing platform software for CF2 instruments may not be compatible with RDL Instruments, contact the platform manufacturer for more information. 

Upgrade to RDL: Rockland will continue to service CF2 Persistor based instrumentation while parts are available, however we recommend upgrading to the RDL if possible.  The RDL was designed to enable an efficient replacement of the CF2 Persistor in existing instrumentation. For more information or if you would like to upgrade an existing instrument from CF2 to RDL, please contact 

Technical Support for RDL: The Rockland Support Team is standing by to provide support and training for the new RDL. Please contact with and questions or concerns. 

For a complete overview of the Rockland Data Logger please download Technical Note – 052 Rockland Data Logger Overview and Comparison with CF2 Systems available on our Technical Note Download Page. We also have a RDL Integration Guide available to platform integrators by request.

What is it about?

Why are we interested in the surface of the ocean? The surface of the ocean is the interface between the ocean interior and atmosphere. Heat, gases and momentum are exchanged at this boundary, this has implications on weather and climate.

How did we measure it?

We went out to the North Atlantic, off the continental shelf, in September 2012 for a month. We deployed an Ocean Microstructure Glider (yup, known as OMG!!). This instrument is pretty new and pretty special!

Rockland Scientific Partners with Big Blue Ocean Cleanup to Offset Ocean Waste

Rockland is pleased to announce a corporate partnership with Big Blue Ocean Cleanup (BBOC), one of the world’s leading independent ocean cleanup non-profit foundations.  BBOC prevents and removes ocean pollution to minimise the effects of human development. At Ocean Business 2019, Rockland kicks off an annual donation pledge to BBOC. In April, Rockland transferred £20 for every instrument shipped in the 2018 calendar year.

As a specialist in the design and manufacture of oceanographic research instrumentation, Rockland plays an active role in better understanding of the world’s oceans.  At the same time, Rockland recognizes the life-cycle impacts of their products, which are the result of the operational nature of ocean research instruments and the challenging conditions in which they are deployed and recovered.

Rockland has made significant efforts to minimize its ocean impact, acknowledging two potential sources of ocean waste: i) discarded ballast weights from autonomous deep-sea profilers and ii) instruments lost at sea.  To mitigate the effects of the intentionally dropped ballast weights, Rockland has designed them to be made entirely of ferrous metal, which will oxidize in the ocean water. To minimize equipment loss, Rockland incorporates safety factors in the equipment design, and provides operational training to its customers.

“Partnering with Big Blue Ocean Cleanup is aligned with Rockland’s vision of ocean stewardship, and our efforts to minimize the life cycle effects of our instruments” says Rockland President, Dr. Fabian Wolk, “…and similar to our customers, Big Blue values scientific research and technology development, and is active in all of the world’s oceans.”

About Rockland Scientific: Rockland is dedicated to the measurement of turbulence in oceans, rivers, lakes and laboratories.  Their measurement systems comprise of ship-board profilers as well as modular sensor payloads for deployment from gliders, floats, and moorings. They accurately detect turbulence levels, from the most energetic tidal channel down to the deep ocean.
